A circle with a radius of 4 in. is dilated by a scale factor of 1/2. What will be the circumference of the circle after dilation?
A. 2(pi) in.
B. 4(pi) in.
C. 16(pi) in.
D. 24(pi) in.
Answer:
4 [tex]\pi[/tex] in.
Step-by-step explanation:
C = 2[tex]\pi[/tex]r
The circumference of the circle after dilation is
C = [tex]\frac{1}{2}[/tex] (2)(4)[tex]\pi[/tex] = 4 [tex]\pi[/tex] inches.

204, 200,196,... find the 31st term
Answer:
31st term = 84
Step-by-step explanation:
Given:
204, 200,196,...
Find:
31st term
Computation:
204, 200,196,...
First term a = 204
Difference d = a3 - a2
Difference d = 196 - 200
Difference d = -4
An = a + (n-1)d
A31 = 204 + (31-1)(-4)
A31 = 204 - 120
A31 = 84
Answer:
84

hich correctly explains how to estimate 33 percent of 87?
Round 33 percent to 20 percent and 87 to 80. Think of 20 percent as 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 30 percent of 80 is 8 + 8, which is 16.
Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 35 percent and 87 to 90. Think of 35 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 35 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 40 percent and 87 to 80. Think of 40 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 40 percent of 90 is 8 + 8 + 8, which is 24.
Answer
The anwser is C - Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.
Step-by-step explanation:
I got the anwser correct first try on the quiz.
Hope this helps!
Answer:
B: Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.

on the following unit circle, \thetaθtheta is in radians. a unit circle with an angle from the positive x-axis to a ray labeled theta. the point where the ray intersects the circle is labeled 0.54, 0.84 and is in the first quadrant. a unit circle with an angle from the positive x-axis to a ray labeled theta. the point where the ray intersects the circle is labeled 0.54, 0.84 and is in the first quadrant. without a calculator, evaluate the following expressions to the nearest hundredth. expression value \sin(\pi-\theta)sin(π−θ)sine, left parenthesis, pi, minus, theta, right parenthesis \sin(\pi \theta)sin(π θ)sine, left parenthesis, pi, plus, theta, right parenthesis
The value of sin(π-θ) is equal to 0.84 and sin(π+θ) is equal to -0.84.
We are given a unit circle.The radius of the unit circle is 1.The point of the intersection of the ray and the unit circle is (0.54, 0.84).The height of the trigonometric triangle formed using the ray, and the angle (θ) is 0.84.The base of the trigonometric triangle formed using the ray, and the angle (θ) is 0.54.The hypotenuse of the trigonometric triangle formed using the ray, and the angle (θ) is equal to the radius of the circle, i.e., 1.sin(θ) = height/hypotenusesin(θ) = 0.84/1sin(θ) = 0.84sin(π-θ) = sin(θ) because the angle is in the second quadrant where the sin function is positive.sin(π-θ) = 0.84sin(π+θ) = -sin(θ) because the angle is in the third quadrant where the sin function is negative.sin(π+θ) = -0.84Trigonometry is a department of arithmetic that research relationships among facet lengths and angles of triangles. the sector emerged within the Hellenistic international in the course of the 3rd century BC from programs of geometry to astronomical studies

What value of m makes the equation true? 2(m+1.5)=m+10
Answer:
2(m+1.5)=m+10 m=7
Step-by-step explanation:
Distribute 2 to the m and the "1.5". You get 2m+3
You then drop the m+10 and the equation is 2m+3 = m+10
After that, you subtract the "m" over to the "2m" which becomes m+3 = 10
You then subtract the 3 over to the 10 which finally comes to m=7
Kay walks upstairs to make her legs stronger. Every day at work, she walks up 9 flights of stairs. If there are 13 steps in 1 flight of stairs, how many steps does Kay climb in 5 days at work? If you sleep 7 hours every night how many hours are you AWAKE in a year? Tips: There are 24 hours in a day. There are 365 days in a year.
Answer: See explanation
Step-by-step explanation:
Every day at work, Kay walks up 9 flights of stairs. If there are 13 steps in 1 flight of stairs, how many steps does Kay climb in 5 days at work?
The number of steps she walks in a day will be:
= 13 steps × 9
= 117 steps
Number from steps in 5 days will be:
= 117 steps × 5
= 585 steps
If you sleep 7 hours every night how many hours are you AWAKE in a year?
The number for hours awake in a day will be:
= 24 hours - 7 hours
= 17 hours
The number for hours awake in a year will then be:
= 17 hours × 365
= 6205 hours
